WASHINGTON (AP) — The White House is warning Chinese President Xi Jinping (shee jihn-peeng) against trying to wait out President Donald Trump in the ongoing trade dispute between their countries.

The warning from National Economic Council director Larry Kudlow comes ahead of the two leaders’ high-stakes sit-down Saturday in Argentina.

Kudlow says the Trump administration has been “extremely disappointed” by China’s engagement in trade talks but the meeting between Trump and Xi on the sidelines of the Group of 20 summit could be a game-changer.

Kudlow adds that if the U.S. doesn’t get “satisfactory” responses to its trade positions more tariffs will be imposed. Kudlow says he hopes the Chinese understand Trump is “not going away.”

China’s foreign ministry has said a recent phone conversation between Xi and Trump about trade and other issues was “extremely positive.”
